Deprecated setup.cfg used in [email protected] version not compatible with Python versions 3.10 and above

[ghost]

Description

pip install -r requirements.txt fails on Python 3.10 and 3.11 due to deprecated setup.cfg in pyyaml 5.4.1 using license_file instead of license_files . According to PyYaml this problem was fixed and recommended version is 6.0.1.
Fixing this issue may require to update requirements to accept pyyaml>=5.4.1.

              By 2023-Oct-30, you need to update your project and remove deprecated calls
              or your builds will no longer be supported.
